To help show them off, we’re giving away this Athleta Tinker Tank (valued at $44) to one lucky Well+Good reader. The sporty side of this moisture-wicking racerback with a built-in bra is balanced by its relaxed, feminine fit and side-tie drawstring. (If this popular tank is not available in your size or color choice, Athleta will help you pick out an equally appealing alternative.)

For arm-toning homework, we’re also giving away a glamorous set of Italian-designed Technogym Wellness Weights, which sell at the new Technogym showroom in Soho for $103. They’re just a pound each, making them good for a run or for travel.
